Here we go, answering some questions.
00:02
So as i draw these really quick graphs, imagine that they are beautiful graphs that you would see in your textbook.
00:10
Okay, so we have, on one graph, populations that are about 25 people each, so they are pretty small populations.
00:21
And on the other graph, we see populations of 500.
00:25
Okay, at the moment, we are starting with allele frequencies where it's half dominant, half recessive.
00:33
And over time, the populations end up doing this when they are the small number of 25.
00:46
And when there's 500, we end up doing this.
00:56
Okay, so first off, what are we seeing? well, you see that in populations that are really small, genetic drift happens more dramatically.
01:19
Whereas in populations that have a size of 500, which is significantly larger than the other populations, it happens, but not very much...
